Videoslots Casino has just added the latest alchemy themed slot from Pragmatic Play titled The Wild Machine which is an unusual 5×5 reel slot with 40 paylines, along with the regular reels there are also extra small reels to the sides and top that can be randomly activated in the base game by the professor creating a diamond-shaped reel set which can then create 7 of a kind wins which pay considerably more than the regular 5 of a kind wins.
The main bonus feature is triggered by landing 3 scatters on the middle reels which then takes you to a bonus wheel were a variety of stake based cash prizes can be won (multiple if lucky) or you can trigger the main free spins options.
The bonus round does seem to trigger quite frequently but expect to win the stake-based prizes several times in between triggering the free spins round. If you do manage to trigger the free spins option you then have to choose between a wilds reels option or sticky wild option.
in our playtests both are capable of producing very nice wins, the sticky wilds option is much more volatile as this is also played on the diamond-shaped reel set which allows 7 of a kind wins but is very dependant on landing multiple sticky wilds early in the bonus as you do only get 5 free spins with this feature.
Certainly, you will need a lot of patience to play this slot as whilst triggering the bonus wheel is quite frequent you need to be persistent to see both the free spins options.
If you want more consistent bonus rounds opt for the Wild Reels option, if you want maximum volatility and win potential take the Sticky Wilds free spins.
